|I’ve been following a lot of tutorials to create Curve Tri-Part brushes; everything seems to be OK but when I try to subdivide the resulting geometry, Zbrush freezes with the message, “Subdividing Visible Polys” - this happens even with very low-resolution brushes. Oddly, the Tri-part brushes included in 4r6 do not cause this freeze on Subdivision - am I missing some crucial step in the process? I suspect it may have something to do with welding verts. Thanks, looking forward to 4r7!

unmask everything and see if you get the same issue
Thanks, I checked that out though and masking wasn’t the issue; however, I may have found it. When I make my IMM Curves from most initialized poly meshes - a cylinder, for example -they have tiny holes at each end… And Zbrush freezes up when I try to subdivide. When I make them from a watertight poly cube, they seem to subdivide without crashing Zbrush. Going to do some more tests and report back when I’m sure this works; hopefully this helps out anyone else that may have run into the problem!
If anyone finds this thread, here’s the solution to the problem I was having with Tri-Part curve brushes:
If you make the Tri Part brush from an open-ended, initialized primitive Polymesh 3d like a cube, sphere or cylinder, the curve will work but ZBrush will freeze while Subdividing Visible Polys if you try to subdivide the mesh. You have to either Dynamesh or Close Holes before splitting and merging the three poly groups for your Tri-Part mesh brush.
My solution has been to start with a closed (i.e. “watertight”) Polysphere when I sculpt the geo for my Tri-Part brushes… seems to be working great, as I can subdivide the resulting curve meshes without the Freeze.
Hope this helps anyone that runs into the same problem.
